Patent GB-1495497-A (GB)
Title: Candle making
IPC: C11C5/02
Filed: 1974-11-18
Abstract: 1495497 Moulding candles ALPENHOF DESIGN Ltd 18 Nov 1974 [17 Aug 1973] 39114/73 Heading B5A [Also in Division C5] A candle carrying a design in relief is moulded by printing a 2-dimensional representation of the design on to a master member, converting this to a 3-dimensional pattern on the master member, and moulding the candle itself or a final or intermediate mould for the candle against the master member. The desired design is screen-printed or photographed on to and then etched into a printing plate either as a negative for casting a sheet of wax for wrapping about a wax core to form a candle, or as a positive for carting a flat silicone rubber mould (not shown). A flat sheet of wax is cast in this mould and either applied about a wax core to make a candle or about a wax or wooden core to form a model 64 for casting a final mould 68. The sheet of wax corresponds to the part 18 of the finished candle. The wax or modelling clay pieces correspond to the ribs 14, 16 and 24 and are attached to complete the model 64. The model is inverted in a moulding cylinder 50 and is located by a hollow element 60 and a pin 66 while a silicone rubber mould is cast about it. The mould 68 is removed from the cylinder 50 and slit down one side for removal from the model. It is replaced in the cylinder 50 for casting the relief parts 14, 16, 18, 24, &c. of a candle about a plain wax core 2 which has had the tapered end 6 dip coated with a layer 10. The candles may be triangular or square in section and the recesses of the design may be blackened by painting all over and rubbing off the paint on the raised portions. The model may be made from a curved printing plate to avoid using an intermediate mould.

Abstract: 1,269,242. Trailer hitches. REESE PRODUCTS Inc. 8 Aug., 1969 [26 Aug., 1968], No. 39823/69. Heading B9T. A trailer hitch comprises a member 10 for connection to a towing vehicle and carrying at its trailing end a bracket 26 which mounts a towing ball, the bracket detachably receiving for movement about a vortical pivot axis a spring bar 60 supported at its rear end by a chain 82 from a trailer draw-bar 108, the length of the chain being adjustable to vary the tension in the bar 60, thus distributing the drawbar load between the towing vehicle and trailer. The forward end of the draw-bar is formed with a socket to engage the ball. The length of the chain is varied by screwing in nuts 90 on a threaded bolt supporting the chain. The forward end of the spring bar is held in a carrier 62 formed with pins 70 and 74 which engage in slots 42, 49 respectively in the bracket 26. The slots 42, 49 are open at their rear and front ends respectively to enable the carrier to be detached from the bracket and the opposite ends of said slots are formed as abutments for the pins. The draw bar 108 may be replaced by an A-shaped draw bar having a cross-piece from which the free end of the spring bar is supported.

[Also in Division H3] Oscillations are generated in a semi-conductor device comprisng at least first means to pass a direct current through a semi-conductor body maintained at a temperature low enough to produce negative resistance characteristics, a second means to apply a magnetic field perpendicular to the current and a third means to lead out the oscillations generated in the device, perpendicularly to both the electric and magnetic fields said third means comprising a right parallelipiped semi-conductor bar one end surface of which is in conjunction with a side surface of the body. A Ge semi-conductor body 9 doped with In and compensated with Sb has a Ge semi-conductor bar 11 having a PN junction at one end 10, disposed against a side thereof. The surfaces of the two semi-conductors are optically flat and the mutually facing sides are optically parallel. The whole device is immersed in liquid He and a direct current applied together with a magnetic field at right angles thereto. Oscillations generated in 9 are led out through 11 which acts as a waveguide and are detected by device 12. The relationship between the frequency of the oscillations and the various parameters, e.g. magnetic field, dimensions and impurity concentration, is expressed mathematically. The semi-conductor 9 may also be made of Si or an A<SP>III</SP>B<SP>V</SP> compound, e.g. InSb or GaAs. It is stated to be known that when a cryosat doped with a deep trap level is irradiated by light of extremely low intensity the value of critical voltage which gives rise to negative resistance will increase.

Filed: 1974-09-19
Abstract: 1490217 Magnetic bubble detectors PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Sept 1974 [22 Sept 1973] 40870/74 Heading H3B Magnetic bubbles are detected by energizing a magneto-resistive element 2 with a measuring current, modulating the bubble diameter by a magnetic field produced by an alternating current (which may be the measuring current), and detecting a component of the output of element 2 which has a frequency different from that of the measuring current. This prevents interference of the output by rotating propagating field components. The modulating current flows in a nickel alloy magneto-resistive element 2 or in a further current loop (6, Fig. 2, not shown) encircling it, in which case A.C. or D.C. flows in the element 2. The detector output is shown to have a D.C. component and harmonics of the modulating frequency, any of which may be filtered for utilization. Alternatively the sum or difference of the alternating currents in the two conductors may be selected. Reference has been directed by the Comptroller to Specification 1,372,516.

A receptacle for a tab or pin formed from a spring-tempered sheet metal stock comprises a pair of inwardly - converging contact blades 1 and a pair of flexible sidewalls 3, which are rigidly connected together at only their ends, so that if the tab or pin is slightly misaligned when inserted, it moves the mouth of the receptacle laterally to more nearly align the tab or pin. As shown, the sidewalls are connected at the mouth end by a web 4, a web 5 at the other end is soldered or crimped to a post 8 and the walls are formed with stops 6 so that when the tab or pin engages one of the blades, the end 2 of the blade abuts stop 6 to cause the receptacle to bend about bowed portions 7. The blades may alternatively have outwardlydirected ends that engage the sidewall directly, Fig. 4 (not shown). In a further form, Fig. 6 (not shown), the mouth has rigid inclined surfaces (14) to engage the tabs or pins.

Abstract: 970,161. Cam mechanisms. THOMPSON RAMO WOOLDRIDGE Inc. Dec. 7, 1960, No. 42136/60. Heading F2K. [Also in Division F1] In an overhead valve operating mechanism for an I.C. engine (see Division F1), the rocker arms for the inlet and exhaust valves are both associated with a single cam 32 on an axially adjustable cam-shaft 31. The axial movement of the cam-shaft 31 is controlled by a centrifugal governor 54 in which balls 61, 62 move outwardly along grooves 64, 63, as the engine speed increases, and force a plate 58 and the cam-shaft 31 to the right against the action of a spring 52. The cam 32 has an axially changing profile which may be of such form as to provide an alteration in the valve timing, the valve lift or both upon the axial movement of the cam-shaft 31. The axial movement of the cam-shaft can be controlled by a device responsive to load, or by a hand-operated mechanism, either directly or through a servo device. The valve clearances are adjustable automatically, or manually by means of a nut associated with each rocker arm.

Abstract: 1,241,041. Resisting pivoting. RECARO A.G. 11 Sept., 1968 [16 Sept., 1967], No. 43205/68. Heading E2F. [Also in Division A4] In a hinge arrangement, for adjusting the inclination of the back seat frame 2 of a vehicle seat, arm 11 is raised to allow wedges 7 and 8 to be retracted, by springs 27 and 28, from jamming relationship with the teeth of rings 4 and 5; so that parts 5-11 may be rotated about hinge pin 3. Sudden movement of the frame 2, with the arm 11 in the raised position, returns one of the wedges 7 or 8 to the jamming position, since the spring 27 or 28 is stressed to accelarate the wedge and thereby introduces lost-motion. During normal adjustment, gear ring 5, which is rotatably mounted on eccentric 6, rolls around gear ring 4, which is fixed to stationary seat frame 1. In a modification (Fig. 5, not shown), the lever 11 may be raised beyond the normal adjustment position to disable wedges 7 and 8 from responding to a sudden movement of the frame 2.
